Abstract
In a lever drive (11) for a vehicle seat adjuster, in particular in a motor vehicle seat, having a drive lever (17) which can be manually moved, at least one driven lever (21) operatively connected to the adjuster, and at least one transmission means (25), which transmits a torque acting on the drive lever (17) to the driven lever (21) with a transmission ratio, the transmission ratio changes as a function of the transmitted torque.
Claims22
A lever drive for a vehicle seat adjuster, comprising:
- a drive lever mounted so that the drive lever can be manually moved;
- at least one driven lever mounted for moving relative to the drive lever and operatively connected to the adjuster;
- and
- at least one transmission means for:
- transmitting a torque acting on the drive lever to the driven lever with a transmission ratio, and
- changing the transmission ratio as a function of the transmitted torque.

A lever drive for a vehicle seat adjuster, comprising:
- a pivotably mounted drive lever that can be manually pivoted and includes a rolling guide;
- and
- at least one pivotably mounted driven lever which is operatively connected to the adjuster and includes a rolling cam which bears on the rolling guide,
- with the rolling cam and the rolling guide being configured so that the rolling cam carries out a rolling movement on the rolling guide in response to a pivoting movement of the drive lever and thereby transforms the pivoting movement of the drive lever into a larger pivoting movement of the driven lever.
1 more element
A lever drive for a vehicle seat adjuster, comprising:
- a base;
- a drive lever mounted for being manually pivoted relative to the base;
- at least one driven lever mounted for pivoting relative to the base, wherein the driven lever is operatively connected to the adjuster;
- and
- at least one control element that is pivotably mounted to the base, is movably coupled to the drive lever, is movably coupled to the driven lever, and is biased, so that the control element is operative for:
- transmitting a torque acting on the drive lever to the driven lever with a transmission ratio, and
- changing the transmission ratio as a function of the transmitted torque.
